Pesticides have been frequently used in agricultural fields. Due to the expeditious utilization of pesticides, their excessive usage has negative impacts on the natural environment and human health. This review discusses the successful implications of nanotechnology-based photocatalysis for the removal of environmental pesticide contaminants. Notably, various nanomaterials, including TiO, ZnO, FeO, nanoscale zero-valent iron, nanocomposite-based materials, have been proposed and have played a progressively essential role in wastewater treatment. In addition, a detailed review of the crucial reaction condition factors, including water matrix, pH, light source, temperature, flow rate (retention time), initial concentration of pesticides, a dosage of photocatalyst, and radical scavengers, is also highlighted. Additionally, the degradation pathway of pesticide mineralization is also elucidated. Finally, the challenges of technologies and the future of nanotechnology-based photocatalysis toward the photo-degradation of pesticides are thoroughly discussed. It is expected that those innovative extraordinary photocatalysts will significantly enhance the performance of pesticides degradation in the coming years.
农药在农业领域被频繁使用。由于农药的迅速利用，其过度使用对自然环境和人类健康产生了负面影响。本综述讨论了基于纳米技术的光催化在去除环境农药污染物方面的成功应用。值得注意的是，已经提出了包括 TiO、ZnO、FeO、纳米零价铁、基于纳米复合材料的各种纳米材料，并在废水处理中发挥了越来越重要的作用。此外，还详细回顾了包括水基质、pH 值、光源、温度、流速（保留时间）、农药初始浓度、催化剂用量和自由基清除剂在内的关键反应条件因素。此外，还阐明了农药矿化的降解途径。最后，彻底讨论了技术面临的挑战和基于纳米技术的光催化在光降解农药方面的未来。预计那些创新性的非凡光催化剂将在未来几年显著提高农药降解的性能。
